Application filed March 22, 1927. Serial No. 177,275.

This invention relates to automobile appliances and more particularlytoa novel lock for the steering gear of motor vehicles.

One of the primary objects of this invention 5 is to provide a lockcarried directly by the steering column of any auton'iobile forpermitting the expeditious wheel shaft, so that unauthorized personswill locking of the steering be prevented from taking the vehicle byreason of their inability to steer the vehicle.

Another salient feature of the invention is to provide a combinationsteering wheel lock embodying a casing connected directly withthe'steering column and a locking bolt connected with the casing forprojection into and out of locking engagement with. the steeringwheelshaft, the bolt being held in a locked position by locking ringsrotatably associated with the casing and mountedabout the looking bolt,the rings havlng means for permit ting the proper alinement thereof, toallow' thebolt to be slid to out of engagementwith the steering wheelshaft. 7

an inoperative position A still further'object of the invention is toprovide a combination lock for steering wheels of the above characterwhich will be durable and efficient 1 simple and easy to tion of thearrows illustrating the means of" associating the combination lock withthe the construction of the in use, one that will be manufacture, andone which can placed upon the marketand incorporated with a conventlonalsteering col umn at a small cost.

With these and other objects in view,the

invention consists in the novel constructi on,

arrangement and formation of parts, as will be hereinafter morespecifically described, claimed, and illustrated in the accompanyingdrawing, in which drawings: v

Figure 1 is a side elevation of a steering wheel column-showing theimproved combination lock associated therewith,

Figure 2 is a transverse section of the column taken on the line 22 ofFigure 1 looking in the direction of the arrows showing the combinationlock in top plan.

Figure 3is a longitudinal section taken on the line 33 of Figure 2looking in the direcsteering'column and l0ck,-

Figure 4 1s a Figure 3 looking inrows,

detailsection through 'the' combination lock taken on the line 4-4 of athe direction of the 'ar- '22 in alocked position; v

, igure 5 is a detail section through the look I taken on the line 5-5of Figure 3 looking in 1 the direction of the arroWs, -and nected withthe chassis of the vehicle, (not shown) in any desired way;

The improved combination lock A for the steering column B comprisesacasing 15 hav-' I ing a sleeve'16 formed integral therewith at one endthereof forreceiving-theshell 10-, r

This sleeve can be secured to the shell 10in any preferred way, such asbyspot welding if or the like and as shown, suitable fastening elementsli' are provided for thatqpurpose.

In accordance with thisinventionthe steer ing shaft 11'and theshell 10areprovided respectively with a notch or recess 13 and an so that thesame can be locked in any desired position. However when the shaft is tobe locked against turning movement one of the notches Imust be inaline'ment with the opening 14 in the shell. I The casing 15 is,provided with the later ally extending arm 18 formed on the sleeve atone end, and a head 19 on the arm lying opening 14. If preferred thesteering shaft l'lcan'be prov1dedw1th one or more openings,

parallel with the sleeve 16. The head 19 i and the'sleeve 16 areprovided with alined' openings 20".and 21 respectively through which isadapted to project the cylindrical i locking bolt 22. The locking bolt22 can be j provided witha radially extending elongated lug 23, which isslidablygmountedwithin a' groove 24k formed in the wall of the openingj. The bolt 2 2 is further provided with spaced radially extendinglocking lugs 25 which are arrangedin longitudinal alinement with the"lug ass-and these locking lugs 25 cooperate with the locking rings26'for holding the bolt There maybe as many locking rings 26 as desiredand In the present instance I have shown four of such rings. These ringsare mounted between the sleeve 16 and the head 19 for rotation about thebolt 22 and each ring isprovided with an axial bore 27. The bore 27 ofeach ring 26 is enlarged atone face of the ring as at 28 to provide araceway for the locking lugs 25, so that the rings can be freely turnedabout the locking bolt 22. A vertical- 1y extending way 29 is alsoformedin the bore 27 for communication with the raceway or enlargedportion 28 of the bore, so that when the ring is disposed in apredetermined position, the way 29 will aline with the locking lugs soas to permit longitudinal movement of the locking bolt.

The casingl5 is provided with indicating points 30 and the rings aregraduated and marked around their periphery with suitable lockingengagement with the walls of the notch 13. This will permit the freesteering oi. the vehicle l vhen it is desired to lock the steeringgearagainst turning movement it is merely neces sary to slide the bolt22 inward until the same comes into lockin g engagement with the notch13, afterwhieh the locking rings 21 are turned .to occupy the variouspositions, so that persons unfamiliarwith the combination will ifzoaeaabe prevented from alining the ways 29 and thus operating the bolt. 7

From the foregoing description, it can be seen that I have provided anovel combination lock for the steering column of an automobile, andlike vehicles which will be easy to operate and which will not becomesuddenly out of order and which will be entirely fool and burglar proof.

Changes in details may be made without departing from the spirit orscope of this invention, but: I

What I claim as new is:

A combination look for steering columns comprising a steering columnreceiving sleeve, a laterally projecting arm on one end oi' sleeve, ahead formed on'the arm lying parallel with thesleeve, the sleeve andhead having aligned openings, a locking bolt slidably mounted in saidaligned openings, radially extending locking lugs on the bolt arrangedin equidistantly spaced relation longitudinally of the bolt, lockingrings disposed between the sleeve and head and reatably mounted uponsaid bolt, each of the rings including an annular raceway for receivingthe l1 and a longitudinally extending way coiniiiuni eating with theraceway for permitting movement of the lugs out oi the raceway, and alongitudinally extending elon d, guide lug termed onthe locking bolt ll!gitudinal alignn'icnt with the locking lugs, the head having a radiallyextending notch een'iniui'iieating with the opening therein forreceiving said guide lug, said lug and notch constitutingmeans torpreventing turning movement of the bolt in the openings in the head andsleeve.

In testimony whereof I my si nature.
